While Aristotle (along with, in fact, most rational folks) uses logos, in fact all three can be effective at persuasion, and the most convincing arguments use all three. Note too that people can employ logical fallacies effectively in a persuasive piece or argument, as long as the opposition does not "catch" them doing it.

This is typically the final and strongest part of an argument, though also the most likely to be fallacious. Emotional arguments are best used to move others to action,[5] and go a long way to help when the logic is not in the speaker's favor. Generally, pathos is discouraged and politicians who use it are quickly called out by their opponents as scaremongers. Not all emotions have to be negative to be effective, though; a good speaker can throw plenty of humor and sympathy into a speech to control the audience.

Emotions should always appear to be under control, if just barely; uncontrolled passion is generally too much to convince an audience.

Kairos is the art of using the right timing for an argument.[6] This generally comes down to common sense — an argument based on reputation will work best immediately after accomplishing something, an argument based on logic will work best when the audience is pleased and willing to listen, and an argument based on emotion will work best in a time of crisis.
